Application tiled September 6,1898. Serial No.690,278. (No model To @ZZ when?, it may concern,.-

Be it known that l, ANDREW G. SHEAK, a citizen ot the Unit-ed States, residing at Binghamton, in the county of Broome and State of New York, have invented a new and useful lVater-Filter, oi' which the following is a speciiication.

The invention relates to improvements in water-tilters.

rlhe object oi the present invention is to improve the construction of that class of waterlilters in which natural or articial stone is employed as a liltering medium and to provide a simple, inexpensive, and efticient one designed to be used in connection with a water service or supply pipe and adapted to iilter water in large and small quantities and capable of cleaning itself automatically, and thereby obviatin g the necessity of removing it and taking it apart to accomplish this result.

rlhe invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a vertical sectional view of a water-filter constructed in accordance with this invention. Fig. 2 is a horizontal sectional view on line 2 2 of Fig. l. Fig. 3 is a detail view of the frame which supports the filtering-cylinder. Fig. et is a detail view of the cover.

Like letters o reference designate correspondin g parts in all the figures of the drawings.

A designates an outer cylindrical casing provided at its upper end, which is enlarged, with interior screw-threads, which are engaged by corresponding screwthreads of a hollow coverB, fitting within the enlarged upper end of the casing and bearing against and supported by the shoulder or seat formed by such enlargement. This shoulder or seat h receives a suitable packing, which is interposed between the same and the cover to form a water-tight joint and prevent the escape of water from the top of the filter. The Casin g is provided on its interior with parallel vertical flanges a, forming a vertical groove or way adapted for the reception of a brush O and capable of holding the same in opera tive position. From the center of the bottom of the casing depends a tube e', having an el;H teriorly-threaded lower end, and around the opening at the upper end of the tube is a socket J, forming a race for a series of antifriction-balls K, upon which rests and revolves a frame D, which carries a filtering cylinder or casing E. The casing A is provided near its outer edge with an opening F, located at the bottom of the said casing and provided with a depending threaded iiange adapted to receive a faucet or a plug which is designed to provide for a flow of water through the opening F for a purpose hereinafter described. r`he bottom of the casing is also provided with a threaded opening located directly beneath the groove or way formed by the parallel flanges of the casing, and this opening, which receives a removable plug II, provides for the introduction and removal oi the brush C and enables a new brush to be supplied when necessary. The plu g H, which tits inthe opening 7L', is provided with a head located at its lower end and forming a seat for a suitable packing.

The cover B, which is hollow, forms an interior chamberj and is provided at its top with an opening N, interiorly threaded and adapted to screw on a water-pipe. The bottom or lower wall N is inwardly or upwardly offset aud is provided at its center with a socket Z, forming a bearing for a shaft or journal m of the frame D. The inwardly or upwardly offset bottom N of the cap or cover otl the casing forms a lower recess, in which is arranged a water-wheel L and which is substantially circular. The walls of the rccess formed by the depending annular portion of the cap or cover consist of a series of tapering portions n, forming radially-ar ranged shoulders and provided with openings or passages o, extending from the interior chamber j and having their lower terminals arranged to eject the water horizontally. The curved faces n2 extend gradually inwardly and are adapted to direct the water discharged from the openings o against the water-wheel, whereby the latter will be rotated. The streams of water ejected from the passages or openings o are delivered upon the water- IOO wheel in a direction substantially tangential with relation to the same and to the casing, and as they are arranged at intervals, as clearly illustrated in Fig. 4 of the accompanying drawings, it will be clear that a positive rotation of the Water-wheel is effected.

The frame D, which supports the inner iiltering casing or cylinder, comprises an upper Adisk or plate L', a'lower disk or plate M, and

vertical bars t, connecting the top and bottom of the frame and located at opposite sides thereof, as clearly illustrated in Fig. 3 of the accompanying drawings; but the number and position of the bars may be varied, if desired. The shaft or journal m projects upward from the top of the frame, which is provided on its lower face, at its periphery, with an annular groove s, formed by inner and outer concentric ribs or flanges r and q and receiving the upper edge of the filtering-cylinder E. The bottom of the frame is provided on its upper face with an annular groove s', receiving the lower edge of the filtering cylinder and formed by concentric anges similar to the groove s of the top of the frame. The connecting-bars t are secured to or formed integral with the upper disk or plate L and have their lowerl ends fitting in grooves u of the lower disk or plate M, and these bars are of sufficient length to prevent the top and bottom of the frame from exerting any strain on the filtering-cylinder. The grooves are designed to be filled with suitable impermeable cement, which secures the filtering cylinder or casing to the frame in such a manner that no water can enter the former except by percolatin g through the cylinder, whereby the water is thoroughly purified. The inner filtering-casing, which may be made of natural or artificial stone, porcelain, baked clay, or the like, may also be of any other desirable configuration which will permit it to rotate within an exterior casing.

The lower plate, which forms the bottom of the frame, is provided with a central opening fu, from which depends a tube w, which extends through and revolves within the depending tube z. rThis inner tube w, which projects somewhat beyond the tube z, is provided with screw-threads at its lower end and receives a nut e, forming a seat for a suitable packing. The bottom of the frame is enlarged at the upper portion of the tubevw to provide a cone-bearing fte rest on the antifriction-balls 7c.

An elastic packing g, of rubber or other suitable material, is placed on the upper portion of the tube .e and is engaged bya thumbnut O, mounted on the threaded portion of the tubezand bearing against the said packing g with just sufficient pressure to make a water-tight joint. When the thumb-nut O is arranged in this position, it is engaged by the packing and the nut e. The thumb-nut O is provided with an annular groove forming a lower supporting-:flange p, which is engaged by screws 7s of a water-distributer P.

rllhe water-distributer P consists of a tube or pipe arranged on the lower end of the thumb-nut and swiveled to the same by the said screws A stop-cock R depends from the lower portion of the tubular portion ai, and a lateral pipe y extends from one side of the distributer.

The brush C, which moves freely in the groove or way formed by the fianges a, is forced against the surface of the filtering cylinder or casing by springs c', interposed between the back of the brush and the outer casing.

When it is desired to clean the filtering cylinder or casing, the stop-cock R is opened, the thumb-nut O is screwed up tightly against the elastic packing g to raise its lower end from the seat of the nut e, and the faucet or plug at the opening F is opened or removed to permit the water inside the casingA to escape freely. The pressure being removed from the interior of the lower portion of the lter, the water is ejected forcibly through the openings oof the cap or cover into the recess of the same, thereby causing the waterwheel, which is mounted on the shaft or spindle fm, to revolve rapidly. This causes the filtering cylinder or casing to rotate against the brush, which, together with the now of water, will rapidly and thoroughly cleanse the filter of all accumulations. The water which escapes around the tubes w when the thumbnut O is raised to remove the pressure from the nut e fiows through the open stop-cock R. After the filter is cleansed the shut-off or faucet is closed atF and the thumb-nut O is turned down firmly on the packingof the nut e. The stop-cock R is also closed and the water entering the filter must pass through the filtering cylinder or casing and may be conveyed by the pipe y into a suitable receiving vessel or tank.

The invention has the following advantages: The filter, which is adapted to be attached to an ordinary service or supply pipe, is simple and comparatively inexpensive in construction, and the rotary filtering cylinder or casing and the means for rotating it are supported on ball-bearings, and the brush, which yieldingly engages the filtering cylinder or casing, is removably mounted in the device and may be readily replaced by a new brush when necessary. The ltering cylinder or casing through which the water percolates is supported within the frame, which has its top and bottom spaced apart, so that they do not exert any pressure or strain on the said cylinder or casing. The openings for ejecting the water upon the water-wheel have their discharge-orifices disposed tangentially, and the curved inner faces of the tapering portions n of the cap serve to direct the streams of water inward against the water-wheel.

The lateral tube of the water-distributer is adapted to conduct the filtered water to a ysuitable receptacle or ta'nlnwlierethe filtered ICO "water may be stored, and the stop-cock R will enable filtered water to be readily obtained direct from the filter.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacriiicing any of the advantages of this invention, such as varying the configuration ofthe filtering casing or cylinder, the number and arrangement of the connecting-bars t, or providing a casing with a series of iiltering casings er cylinders.
